Outline of Final Research Achievements

Rwt4, a wheat resistance gene against the oat blast fungus, is located at the same locus as Pm10, a wheat resistance gene against the wheatgrass powdery mildew fungus. Southern blot analyses suggested that PWT4 corresponding to Rwt4 is different from Ppm10 corresponding to Pm10.
Rmo2, a barley resistance gene, is effective against various subgroups of the blast fungus. The candidate genomic region with Rmo2 was delimited to 50kb through fine mapping.
